[0002] With the wide application of model unmanned aerial vehicles, their performance in the fields of entertainment, racing and surveying is increasingly valued. Especially in racing and professional surveying scenarios, accurate measurement of flight speed becomes one of the key factors affecting the performance of unmanned aerial vehicles. Existing model unmanned aerial vehicles usually measure speed through GPS speed meters and feed back real-time flight speed to remote controllers for user reference. However, the GPS speed meters in the prior art usually only support a single ordinary precision speed measurement mode and cannot flexibly adjust the speed measurement precision according to different application scenarios, which is difficult to meet the high-precision application requirements. In the prior art, some improved schemes try to optimize the GPS signal receiving module or improve the data processing algorithm to improve the speed measurement precision, but these schemes are still limited to a single precision mode and cannot switch the speed measurement precision in different scenarios. For example, part of the technology enhances the anti-interference ability of the GPS signal to improve the speed measurement precision, but this improvement does not consider the balance between precision and power consumption in different application scenarios. In addition, the existing speed meter design relies on a single hardware module and lacks a flexible mode switching mechanism, which makes it difficult to effectively adapt to various flight scenarios.

[0003] Therefore, it is necessary to provide a GPS speed meter for model unmanned aerial vehicles with multiple precision modes to solve the demand for unmanned aerial vehicle position precision in different scenarios. CONTENT OF THE INVENTION
